SAW-HANDLE.

SPECIFICATION forming part of Letters Patent No. 277,502, dated May 1-5, 1883.

Application filed February 10, 1883. (No model.)

To all whom tt may concern:

Be it known that I, JOHN NE1MEYER,a citizen of the United States, residing at Trenton, Butler county, Ohio, have invented new and useful Improvements in Fastenings for Crosscut-Saw Handles, of which the following is a specification.

My invention relates to devices for securing handles to crosscut-saws, its object being to improve the same in several particulars, as hereinafter pointed out; and to this end it consists in the construction and arrangement of an abutment-piece against which the saw-blade is securely held, and a pin-bolt guided upon the abutment and by its operation holding the saw against the abutments and the abutmentpiece to the handle, all as hereinafter more fully described, and constituting an eflicient, economical, convenient, and durable fastening device adapted to any of the saws in common use.

My invention is illustrated in the accompanying drawings, in which Figure 1 is a side elevation ofa saw-handle and portion of a sawblade, showing my improved connecting devices in position for securing the saw-blade to the handle. Fig. 2 is an end view of the abutthe abutment-piece, and Fig. 4 is a perspective view of the pin-bolt detached and with its nut and washer removed.

In the drawings, to which reference is made by way of illustrating more clearly the following description, A designates the handle, and B the saw-blade to which my improvement is applied; 0, the abutment-piece; D, the pinbolt, and E the thumb-nut by which all parts are held together and the saw connected to the handle for operation.

The abutment-piece consists of a base, 0, curved to seat upon the cylindrical-surface of the handle A, and two lugs or columnar abutments, 0 c, rising parallel to each other from the base a, at right angles with its general length, sufficiently to accommodate the hand of the operator behind the saw-blade when the latter is resting against the ends of the abutments. The operatoris thus enabled to apply his muscular force more nearly-in the line of the saw-teeth instead of above the upper edge of the saw-blade,as is usual in devices of this character. The end faces of the abulments are grooved in the same axial line, as shown at 0 Fig. 3, to accommodate the end of the saw and prevent its lateral displacement.

The pin-bolt Dis formed in three distinct portions-a screw end, 07, a flattened extension, cl, provided with a short stud, p, rising out of the flat face d to engage the saw, and a cross head, 01?, intermediate between the flattened extension and the screw. The fiat face of the extension is so arranged that the saw-blade, when resting upon it and engaging the stud 1), shall be in the axial plane of the screw (Z, extended rearward. The cross-head is a lateral enlargement, whose end faces ,are provided with grooves axially parallel with each other and with the screw d, and adapted to fit and slide between and upon the abutments c c.

The saw-blade is attached by placing fiatwise upon the flattened extension 01, so that the stud p enters through an aperture always provided in the saw-blade, the extension being made of sufficient length to compensate any irregularity there may be in the position of the aperture through the saw-blade with respect to the rear edge of the blade. The pin-bolt is then placed in position, its screw end (I being inserted through an aperture provided in the basec between the abutments of the abutmentpiece 0, and through a correspo'ndin g aperture hored through the handle and its cross-head d between and sliding upon the abutments. The rear edge of the saw-blade being at the same time rested in the grooves 0 of the abutments, the thumb-nut E is applied upon the projecting end of the screw, and with aninterposed washer, e, is screwed down against the handle. Gontinuingits rotation, the pin-bolt is drawn through the handle, and the sawblade drawn taut and rigidly against the abutments.

I prefer in constructing the device to cast or form a slight groove or depression on the side of the stud p nearest the cross-head, as a precaution againstlateral displacementof the sawblade when in operation; but, as the obvious tendency of wear in the use of the device is to create such a groove or depression, I do not deem it a matter of vital importance in the original construction, although preferring it.

It will be observed that the pin-bolt fastenin g as th us constructed is reversible-that is, it operates on either side of the saw perfectly; also, that the base or abutn1ent-piece,with the corresponding washer, can be applied to any handle with'no further preparation than forming acylindrical contour at that part and piercing for the bolt, in which respect the improvement upon a cylindrical ferrule is obvious.

I claim as my invention and desire to secure by Letters Patent 1. In handle-fastenings for crosscut-saws, two parallel abutments risingfrorn aperforated base adapted to seat upon the handle, in combination with'a fastening-boltextending through the perforated base and handle, provided with a cross-head guiding it between and upon the abutments, and an extension beyond the abutments for engaging the saw, and by the operation of the tightening-nut securing the saw rigidly against the abu'tments and all parts rigidly to theliandle, substantially as setforth.
